JAMES F. MOLAUGHLIN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESN E ASSIGNMENTS, TO THE NATIONAL ELECTRIC RAILVAY SYSTEM,

(LIMITEQ) or SAME PLAGE.

ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 332,928, dated December 22, 1885.

Application filed July 1, 1885. Serial No. 170,331.

To all whom it may concern:

Be it known that I, JAMES F. McLAUGH- LIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Electrical Railways,

of which the following is a specication.

My invention consists of certain improvements in the construction of the conduits for the roadway of an electrical railway, as fully 1o described hereinafter.

In the accompanying drawings, Figure 1 is a transverse section of the roadway of an electrical railway embodying my improvements. Fig. 2 is a transverse section,drawn to an enlarged scale,of a modiiication; and Fig. 3 is a section, drawn to an enlarged scale, of one of the line-conductors and its insulating-plate, with their attaching devices.

My improvements have more especial reference to that class of electrical railways in which the conductors are carried in the conduit or conduits alongside of -or between the tracks, and in the drawings I have illustrated the two conduits placed outside of the tracks, but closely adjacent thereto.

A is the roadway between the two tracks C C, which are mounted on the usual longitudinal stringers,B B, supported by the crossties c. Adjacent to the stringers, and in this case outside thereof, I arrange L-shaped bars D, which are supported on the cross-ties c, as shown in Fig. 1, and which may also be bolted to the stringers, as shown in the modiiication, Fig. 2. The vertical portions d of the bars extend up to nearly on a level with the tops of the rails, and are provided with top plates or covers, H, which may be bolted or otherwise secured thereto, as shown in Fig. 1; or these cover-plates may be hinged to the bars D, as shown in Fig. 2, the edges h of these plates or covers projecting over and forming protectingsheds for the electrical conductors carried in the conduit, as hereinafter described. Between the edges of these coverplates and the opposite sides of the conduit, which I have shown as formed by the stringers and rails, is left a space, e, to forni the longitudinal slot for the passage of the contact-rod suspended from the motor-car.

(No model.)

If desired, cement or other suitable bars, e, 5o may be placed in the conduits on the bottom and sides, bounded by stringers and trackrails, to protect the said stringers from the water, and to provide smooth inclined or curved sides, which will allow water and dbris to pass off through lateral passages m, as indicated by dotted vlines in Fig. 1..

I f desired, strengthening-plates I may be secured to the outer sides ot' the bars D, as

shown in Fig. 1, this being more particularly 6o desirable when the said bars are of wood, as shown in said figure. Where the bars D are of metal, as in the modification, Fig. 2, the additional plates, I, are not essential, asjlthe bars may then be rolled or cast with strengthening ribs or flanges.

The electrical line-conductors I prefer to make of wire rods, round in crosssection, as illustrated more fullyin Fig. 3; but they may be of rectangular or any other suitable section. 7o These conductors are secured to the inner sides, d?, ofthe upright portions d of the bars D through the medium of insulating strips or plates G. The conductors are secured to the insulating strips or plates by means of screws g, entering into the back of the conductors, but not passing through the same, so as to leave their outer surfaces perfectly smooth, and the insulating-strips are then securedto the bars D by screws g2.

Vhere the round conductors are employed, the strips of insulating material are grooved, as shown at gu, Fig. 3, to received the conductors.

I claim as my inventiont 1. The combination of the stringers and rails with L-shaped bars D, carrying the conductors, and forming, with the said stringere and rails, conduits therefor, and cross-ties .carrying both stringers and bars, substantially 9c ing-strips G,secured to the bars, and electrical ductors F, and cement bars e, in the conduit conductors F, carried by the strips, snbstanon the side adjacent to the stringers, substantially as described. tally as set forth. A

4. The combination of the rails, stringers, In testimony whereof I affix my signature in 5 and cross-ties with the L-shaped bars D, can presence of two Witnesses.
